If both directories D1 and D2 already exists, and further there is a
filesystem entity D2/D1, "git mv D1 D2" would fail, and we get an
error message that says:
"cannot move directory over file, source=D1, destination=D2/D1"
regardless of the type of existing "D2/D1". If it is a file, the
message is correct, but if it is a directory, it is not (we could
make the D2/D1 directory a union of its original contents and what
was in D1/, but that is not what we do).
The code that decies to issue the error message only checks for
existence of "D2/D1" and does not care what kind of thing sits at
the path.
Rephrase the message to say
"destination already exists, source=D1, destination=D2/D1"
that would be suitable for any kind of thing being in the way.

* Just so that we do not forget what we discussed. It is kind of
interesting that no tests need adjustment for this change, which
make me suspect how good our test coverage is.
This patch has a trivial textual conflict with Sebastian's patch,
but the resolution should be obvious.
